What I claim isg 1. In a single-shaft centrifugal drive, the combination of a hanger, a sleeve member having a gyration bearing in said hanger, a rotatable shalt extending through said sleeve member and having a bearing thereon, a bracket for supporting a motor element secured to said sleeve member, and a projection on said hanger adapted to engage said bracket to prevent its rotation.

2. In a single-shaft centrifugal drive, the combination of a hanger, a non-rotatable sleeve member extending above and having a gyration bearing in said hanger, a rotatable shaft having a bearing upon the top of said sleeve member, a bracket for support gyrate just as, in the arrangement in a motor element extendin below said hanger, said bracket having an aperture to receive said sleeve member and secured thereto at the upper end thereof.

3. In a single-shaft centrifugal drive, the combination of a hanger, a sleeve member having a gyration bearing in said hanger, a rotatable shaft having a bearing upon the top of said sleeve member, a bracket for supporting a motor element secured to said sleeve member above said hanger and extending below said hanger, and a projection on said hanger adapted to engage said bracket to prevent its rotation.

4. In a-single-shait centrifugal drive, the combination of a hanger, a sleeve member having a gyration bearing in said hanger, a bracket secured to said sleeve member above see roe 5. Ina single-shaftcentrifugaldrive, the combination of a hanger, a sleeve member extending above and having a gyration bear- I ing in said hanger, a bracket secured to said 6 at a point below the hanger 1 and will in said hanger and extending below said hanger, a projection on said hanger adapted to engage said bracket to prevent its rotation, a rotatable shaft extending through said sleeve member, and a bearing for said shaft on said sleeve member above said bracket.
